An exponent is a number that tells how many times the base number is
used as a factor. For example, 3^{4} indicates that the base number 3
is used as a factor 4 times. To determine the value of 3^{4}, multiply
3*3*3*3 which would give the result 81.

Exponents are written as a superscript number (e.g. 3^{4}) or preceded
by the caret (^) symbol (e.g. 3^4).

Some facts about exponents:

- Zero raised to any power is zero (e.g. 0
^{5} = 0)
- One raised to any power is one (e.g. 1
^{5} = 1)
- Any number raised to the zero power is one (e.g. 7
^{0} = 1)
- Any number raised to the first power is that number (e.g. 7
^{1} = 7)
